I have a go program with a main.go and a sub.go. When I run it under the debugger, main cannot see the function defined in sub. I tried creating a tasks.json but when I run it nothing happens.]
The MS documentaiton linked is for Node Package Manager and it doesn't state where the identifier for the task is placed in the configuration file
Here is my tasks.json:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "echo",
"type": "shell",
"command": "go run crypto.go sbox.go state.go utility.go"
}
]

I have a task created that runs some unittests via bash_unit.
The bash unit script seems to fail based on its use of which.
If I replace:
CAT="$(which cat)"
and other which referances in bash unit to point to my local commands all runs great.
If I run bash)unit directly all good, but if i run it as a vscode task it fails.
I have simplified the task below to the minimum failure:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "run which",
"type": "shell",
"command": "/usr/bin/which which",
"problemMatcher": [],
"group": "test",
}
]
}
This produces the following:
The terminal process "/bin/bash '-c', '/usr/bin/which which'" failed to launch (exit code: 1).
Any ideas what is happening?
I am writing a CLI in go using VS code editor. I am not able to figure out how to debug a code section.
My directory structure is :
- test
- main.go
- cmd
- login.go
- root.go
I have set breakpoints in login.go but if I run "Start Debugging" in this file, I get error
Can not debug non-main package
Process exiting with code: 1
I tried running debugger in main.go but the debugger won't go to login.go file as I we have not explicitly written test login
API server listening at: 127.0.0.1:48423
A longer description that spans multiple lines and likely contains
examples and usage of using your application. For example:
cd .
Cobra is a CLI library for Go that empowers applications.
This application is a tool to generate the needed files
to quickly create a Cobra application.
Usage:
test [command]
Available Commands:
help Help about any command
login A brief description of your command
Flags:
--config string config file (default is $HOME/.test.yaml)
-h, --help help for test
-t, --toggle Help message for toggle
Use "test [command] --help" for more information about a command.
main.go file
package main
import "test/cmd"
func main() {
cmd.Execute()
}
login.go file
package cmd
import (
"fmt"
"github.com/spf13/cobra"
)
// loginCmd represents the login command
var loginCmd = &cobra.Command{
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("login called")
name, _ := cmd.Flags().GetString("username")
pwd, _ := cmd.Flags().GetString("password")
userInfo := name + ":" + pwd
},
}
func init() {
rootCmd.AddCommand(loginCmd)
// Here you will define your flags and configuration settings.
loginCmd.Flags().StringP("username", "u", "", "Specifies the user")
loginCmd.Flags().StringP("password", "p", "", "Specifies the password for the user")
loginCmd.Flags().StringP("manager", "m", "", "Specifies the environement where user wants to login")

Please guide me how I can see the variable values in debug mode like for variable name. Though using Println is fine, but this source code is part of a bigger project, so I want to see how I can use the debugger ?
Modify your launch.json as below:
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "${workspaceRoot}",
"env": {},
"args": [],
"port": 8080,
"host": "127.0.0.1"
}
]
}
You'll learn that some differences are there from yours.
...
"mode": "debug",
"program": "${workspaceRoot}",
...
You can add flags to the "args": [] array in your vscode settings like this:
"args": ["login", "-u", "username", "-p", "password"]
This will make sure when you run debug you end up in the login command with the given flags.
I am struggling with getting my Visual Studios code task to work. The problem is that it seems like the task/.bat file is not being executed.
VS Code task configuration:
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "My Label",
"type": "shell",
"windows": {
"command": "'c:\\Program Files (x86)\\path\\to\\the\\file.bat${file}'"
},
"presentation": {
"reveal": "always"
},
"group": {
"kind": "build",
"isDefault": true
}
}
]
}
For testing purposes the file.bat contains:
echo "------"
echo %1
echo "------"
The output in Visual Studio Code terminal is:
> Executing task in folder User: 'c:\\Program Files (x86)\\path\\to\\the\\file.bat c:\project\file.abc' <
c:\\Program Files (x86)\\path\\to\\the\\file.bat c:\project\file.abc
Terminal will be reused by tasks, press any key to close it.
I expected that the ${file} argument/value to printed in the console. The problem is that nothing is printed. It doesn't matter if I intentionally make syntax errors in the bat file. From VS Code it seems like the .bat file is not executed at all.
The shell being used is PowerShell
Configuration:
"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\powershell.exe"
Thank you in advance!

You just have a slight syntax error using double quotes and single quotes together.
Change to:
...
"windows": {
"command": "c:\\Program Files (x86)\\path\\to\\the\\file.bat ${file}"
}

I'm trying to create some tasks in Visual Studio Code to run all the tests in my go project.
I usually execute the tests on the command line using:
go test ./...
In Visual Studio Code my tasks.json looks like this:
{
"version": "0.1.0",
"command": "go",
"tasks": [
{
"taskName": "build",
"isBuildCommand": true
},
{
"taskName": "test",
"isTestCommand": true,
"args": ["./..."]
}
]
}
So Build works fine (CTRL + SHIFT + B)
But when I try to run the tests (CTRL + SHIFT + T) the following error occurs:
go: unknown subcommand "./..."
It seems to be omitting the "test" param, but when I comment out the args it runs go test fine.
Any ideas?
THIS MAY BE A BUG
VSCode Reverse Args and Task as of v0.8.0
This may be a bug that still persists in the newer versions. As of v0.9.1 I have not had a chance to test. Prior to 0.9.1 at least one hack worked by reversing the task and it's arg as in the following example:
{
"version": "0.1.0",
"command": "go",
"tasks": [
{
"taskName": "build",
"isBuildCommand": true
},
{
"taskName": "./...",
"isTestCommand": true,
"args": ["test"]
}
]
}
It's hard to believe that this has still persisted until v0.8.0 so there may be a preferred solution that I have not discovered.
Here is a link to a prior post that deals with a similar issue:
Define multiple tasks in VSCode
Scroll down to my answer for more explanation.
Refer to this stackoverflow question:
I am trying to do the same but on Mac. I have the same as above,except instead of
"runtimeExecutable": "node_modules/electron-prebuilt/dist/electron.exe"
I have it as
"runtimeExecutable": "/usr/local/bin/electron"
Since F5 on mac is mapped to screen dimmer, I launched the app from command line as follows:
electron --debug-brk=5858 .
My program launched and ran without breaking.
So I modified keybindings.json like so:
[
{ "key": "shift+ctrl+f5", "command": "workbench.action.debug.play",
"when": "inDebugMode" },
{ "key": "shift+ctrl+f5", "command": "workbench.action.debug.start",
"when": "!inDebugMode" },
]
I tried launching the program by pressing shift+ctrl+f5 - I am still unable to debug my program.
I get the following error:
Error: Connection Failed
when I run node instead of electron, the debugger works fine when the the app is launched from command line
PLEASE HELP!
Thanks in advance
This is your launch.json. The important parts are runtimeExecutable and env. For VS Code 0.8.0, debugging only mostly works using electron 0.30.6.

Install 0.30.6 of electron-prebuilt in your project directory using npm install –-save-dev electron-prebuilt#0.30.6
